Using a mobile app to improve medication adherence for atrial fibrillation patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effectiveness of a medication reminder app combined with bi-weekly video education in improving adherence to apixaban among patients with atrial fibrillation and comorbidities. Participants will be randomly assigned to either a treatment group, which receives both the app and video calls, or a control group that only uses the app. The study aims to measure changes in medication adherence after eight weeks of intervention. By leveraging digital health tools, the trial seeks to enhance patient engagement and medication compliance.
